I'm very happy for you guy

You are still alive . After lots of lay offs 😮

Be positive buddy. Please don't repeat it again

Very very helpful. You are a life saver. I was stuck on this issue for so long. And trying your method solved the issue within seconds. Thank you so much!!!

The only video where i learned this concept properly, amazing

[@anthonyvinay9943]

Simple and Concise. 100% to the point content. Thank you so much for this educational content.

[@suhashari2988]

very helpful. like how you showed what the mock object does using a print statement in service layer.

[@santoshkamat6132]

❤️ you brother. U have solution to each and every problem. May god bless you for the service you are doing towards the people

[@sayanshee6067]

Awesome content, pretty straight forward. Some people are complaining about communication. Don't worry about accent/communication as long as your content is good.👍🏻

[@Javatechie]

Thanks Sayari 😊

[@nikhiljhawar4612]

@@Javatechie Nice and presized content. I just wanted to know when you're getting user with address="Bangalore", then the user returned is having address as "USA". So, could you please help me understand that.

[@ajaydarshanala8051]

@@nikhiljhawar4612 That's a good question. If you see the service method , it has no business logic. as the repository method is mocked here, it really not checking bangalore . It will always give the usa user object, because the method is mocked. In real time, the service method will have business logic to check bangalore, this video helps to understand the concept. @10.34, he used a term "for testing purpose ". Hope this comment helps.

Thanks for covering Mockito. I believe this is Junit 4. Can you please cover more test cases with Junit 5 and with different situations including how to handle exceptions and all?

[@steambassador]

Before this video i watched many others related to Unit test, and the make it more difficult. After watching your video, i started to implement tests directly on my codes!!! thanks for making it simple to understand.

Thanks buddy 😊

its simple, straight and Good

[@nyesExpress]

I'm fairly new to Java (and Spring). I see from the source code that 'UserRepository' is of type Interface. My understanding of @MockBean is that it instantiates an object of type 'UserRepository' within Spring's application container. But this is confusing to me, since I believe that Interfaces cannot be instantiated, only classes. So how does @MockBean instantiate an object of type 'UserRepository', which is an interface? Thanks for the great tutorial btw!

Thank you for useful content...

[@jax40001]

So helpful. I suggest your video to many of my colleagues

[@Javatechie]

Thanks buddy 😊

[@natetolbert3671]

Persistent applications are especially important for which to write tests. You can have a functioning product which gives no errors, deploy said product, and then find out some time later that only half of your data persisted. Or even worse, that the DB overwrites itself each time the program is restarted.

[@Javatechie]

Am not getting you . What you are trying to convey ?

[@vaishalis]

Hi, thank you for the great video. One question - You did not add when(repo.delete).thenReturn(user). Is it not needed in delete case to make sure actual delete method is not called?

Awesome..

[@faizkazi8015]

Hello Sir, Thanks for the session. It really helped just had some doubts. For creating test cases for DAO layer do we mock the methods without hitting db or should perform the db operation and then test?

[@Javatechie]

No you should mock all the db call

also it would be good to say that there is no any sense to test JPA methods which provided for us as an API for free, because its already have been tested. But custom methods with @Query definitely should be tested.

[@divritsaini4993]

Hi on line No 51 how you were able to do assertEquals on two objects. I had to override equals method and implement it to do equals as I was getting false because it was just comparing the reference value of those 2 objects. Please guide me on this. Thanks,

[@blasttrash]

Should you only add tests for service layer? Or should you also add tests for "controller" and "data" layer also? Thanks

[@Javatechie]

We should write for controller layer , please check my mockmvc tutorial

[@thrinathsf1280]

Good explanation. I have one query, you explained unit testing from service to repository flow. What about end to end unit testing with mockito i.e Controller->Service->Repository ?

[@Javatechie]

Already I. Had one video to write test case for controller using mock MVC . It will be more difficult to show test case for all layer in single video.thats why I splited it as separate video.

[@thrinathsf1280]

@@Javatechie ok thanks for the reply. is it possible to write unit tests from end to end using mockito ?

[@Javatechie]

Yes for all layer we can write like controller,service and repository I already uploaded 3 videos using mockito please have a look
